Land Use Change Simulation Using CLUE-s Model in the Watershed of Doroodzan Dam

Land use change is an essential determinant factor in hydrological processes and it affects many of them. Simulation of land use changes, rise in residential and agricultural area and its effects are among the most important issues related to the watershed management. The objective of this research is land use change detection in the past and simulation of future land use using CLUE-s Model. At first, land use map of years 1991 and 2019 was prepared using satellite images and synthetic method. Then, land use change was calculated, and then land use map of year 2040 was simulated using CLUE-s model. The results indicated that the main land use changes in Doroodzan watershed between 1991 and 2019 was the conversion of natural resources to residential area, agriculture and orchards. Accuracy assessment of regression model to investigate condition factors of each land use types using ROC corves demonstrated acceptable accuracy of this method. Using the CLUE-s model, managers and planners can be informed about the future conditions of the region to take into account the problem of land use change in their planning.
